IMPROVEMENT IN Samana-MACHINE.

The Schedule referred to in these Lettere Patent and making part of the same To all whom it may concern Be it known that I, PHILIP D. NoRTncnAF'r, ot' Thurston county, Washington 'lenitory,'have invented certain new anduset'ul Improvements in ShingledVIachines; and I do hereby declare that the following is a full and exact description thereof', reforencc being had to the accompanying drawings. making a part of this application.

My invention consists in providing a shingle-machine with a drag-lifter, constructed and operated in the manner and for the lpurposes hereinafter more fully explained.

My invention further consists in the peculiar oon- -struction and operation of the stop-frame, as hereinafter explained.

My invention further consists of a knife and roller, ou the end of the carriage, and operating in conjunction with the stopframe, as and for the purposes hereinafter set forth.

My invention further consists in forming on the outside faces ot' the carriage a groove, for operating the lower shaving-knife and stop-frame, with respect to each other, andin-the manner and for the purposes hereinafter explained.

And my invention further consists in providing, in the upper rails of the frames, grooves, for operating l the gate-head and right-angled clalnps, as will be presently explained.

Figure 1 is a side View of my machine, wththe carriage in two positions;

Figure 2 i s a longitudinal vertical section through the centre;

Figure 3 is a side view, with side of thc frame o, exposing the side ofthe carriage;

Figure 4 is a vertical cross-section, taken at the line a' a', Iig. 1;

Figure is a vertical cross-section at the line y y, iig. 1; and

Figure is a top viewof the exit end of the 1nachine, broken ott'.

"Similar vletters of reference denote parts in the several views.

A A, 8:0., are standards, upon which the frame and carriage' are mounted.

Said standards extend upward a suitable distano@ and are provided with side rails B B, which have cut therein, on their interior faces, a groove, a, and aliother shorter one, b. The bed of the latter is cut on an incline from rear to frontat its extremity. The frame ofthe machine consists of two side rails C G, one of which has cut, on the expose/d side, a groove, c, and both have a slot cut vertically through, as seen at d d, iig. 6. 4

The one having the groove c is also cut away a short distance, as seen at e, iig. 1', for the purpose hereinafter shown..

The sides G10 are secured to a bottom piece, D, made in two sections, one (the forward) being a little higher than the other, and a. channel, E, leftbetween them.

This channel is underneath the shaving-knife, and

-is returned at the ends, follows up in' a slot prepared for it in the rails, as seen at 0, and into the groove iu the rails G, so that the said knife is raised and lowered, as the groove travels over the bent end of' the knife, as will be presently explained.

The top of the rear section ot'hot-tom D is bevelled with the same inclination as is desirable for the shingle, beginning at .the point' where the stop gpenetrates the said bottom, will be presently explained.

'lhe carriage is composed of two side rails G G, secured by a cross-piece, H, at one end, another, I, at the other.

These rails are grooved, to ride upon the ways F l",

and are cut away a proper distance, to pass over the knives ff.

Lugs h h are secured to the rails, for the purpose of actuating a button, k, secured by a pivot to the top of each of the side rails C (l, and swivelling thereon.

' The rails G G are grooved on their exterior surfaces, as seen at t', and travel over the bent end of one ofthe lower knives ff, anda pin in the-frame of the stop g.

At the rear of the carriage is secured a shavingknit'e, k, in the saine plane with the top side of the bottom D, just in Afrunt-of/t-he stop g, or Where the bevel begins.

The edge ofthe knife is set toward the front of t-h'e machine, and immediately in front of' 'said edge is arranged a roller, J.

Said roller is mounted in a frame, L, which vmoves up and down in slots in the side rails of the carriage, and is governed by a spring, l, secure-d to th crosspiece I.

Behind said knife are 'secured to the end of the car riageV two brackets nl, in' the lower extremities of which is mounted a cylinder or rod, lnfhaving a bent arm, o.

Due end of the cylinder or rod n is provided with crank-lever or arm p, having in its upper end 4au eye, wherein is secured a small rod, r, which passes back, and is secured permanently at one point on the circumference of ythe drag-lifter M, by a short upright, q.

This draglifter is secured to the top of the carriage by staples s, and is free to rotate therein.

Une end of the drag-lifter is provided w'ith a short lever, N, having one end bent at right angles, the bent end adapted to move in the groove c, of the rails C.

A block holder, O, as seen more clearly at iigs. 2 and 4, is arranged securely between the rails G, a distance from the cross-piece H, equal to the length of a shingle.

Said holder is provided with loopst t, through which passes a drop or retaining-rod, P, having thereon a shoulder or stop, r.

The top of the block-holder is provided with two pins, w w, which Amove into slots .in a head-piece, Q, the head-piece `being thus allowed to move up and down upon the pins w w. y

The ends of this head-piece are provided with pins, which move along in the grooves a, in rails B, and it is also provided with two right-angled clamps or springs, as clearly seen at Figure 7 which embrace the droprod P, or not, as becomes -necessary in the course of operation.

The stop g is mounted upon the bottom S of a frame, T, the side of the frame moving vertically in the slot d of the rail O.-

On one of the sides of this frame Tis secured a pin, x, and on the interior of both the upright sides of the frame is another pin, which moves in the grooves i, of the rails 'G ofthe carriage.-

Underneath the said frame 'is arranged one or more springs, y, for the purpose to be explained.

To the side rail C is pivoted a lever, W, which lies upon the pin x on the stop'frame, and israised and lowered thereby.

To' the drag-lifter is secured a drag, U, which, when the machine is ready to start, extends a short distance beyond the back edge ofthe knives ff.

To this i-s loosely pivoted another, V, extending a short distance past the end of the carriage-frame. They 'are both bent down at right angles, like a hook, as

clearly seen in the drawings.

On one side of the bent portion of U isa stop, so that the drag U may rise a short distance before the other, V, is effected.

- The operation of'my improved machine is as follows:

The carriage being. drawn back', ready to start, the block from which .the shingles are to 'be cut is placed upon the bottoml), and between the cross-piece H and block-holder 0'. The drop-rod P, which is sup-` posed to be heavy enough to hold the block steady against the bottom, is then lallowed to drop upon the y top of the block. The machine being now ready=to start, power is applied to the -carriage,.it is driven,

along upon the ways F F, the block extending below Athe bottom edge of the holder O, is forced against the edges of the knives ff, the upper one splitting the shingle off, and lthe lower shaving the underside of' the shingle. l

The lower knife is elevated as the carriage travels, by the incline in the groove t', which travels over the bent end of the knife, and thus the shingle is shaved off onone side, slightly bevelled, andsmooth.

When the carriage has travelled far enough to commence to split the block, the cross-head of the holder O-begins to rise in the groeven,v and the right-angled clamps, having passed out of the slot-s b, are pressed against the rod P, andgrasp it, lso that the crosshead Q carries the said rod up with it, leaving room underneath for the knife to accommodate itself to the grain of the' block.

\Vhen the. carriage has travelled far enough to cut clear through the block, the rear lugs h strike the bevelled sides of the buttons K, and cause them to swivel, so that the opposite ends are thrown from over the slots d, which they' cover, and allow the stop-frame rSides T to fly up, (the pins on the interior of Said frame, which move inthe slots inthe carriage-frame, having found a channel between said grooves, through which to pass,) and bringing with" it the stop g, the pins x, on the outside of the stop-frame, lifting the lever W, which strikes 'the straight end of the short lever N, lifting the same, which revolves the draglifter or cylinder M, causing it to lift the three drags V, and Ao, and, at the same time, depresses the bent end of the lever into. the end of the groove c.

vThe carriage is now started back, the lever N travelling within the groovec, keeps the drags all elevated until the carriage gets back to its starting position,

the groove in the carriage-traine travelling over the pins in the stopframe bring fit down, and the forward lugs 71. h, striking the inside of the buttons, K K, at the moment that the stop-frame has been brought clear down, forces them back to their original position over tbe slots d, and, consequently, on top of ends of the stop-frame, at the. same instan-t that the bent end of the lever N -has arrived at the exit of the channel c, and the drags, by their own weight drop, the tirstone,

.U, dropping on the half-finished shingle, which was left back of the knives ff, the right angle clamps in the cross-head have been released, andthe drop-rod P is again on top the block. The carriage is again started forward, the ,drag U carries the shingle (with its ,under side iinishedl) along, while another is being cut and shaved, and when the second is in the condition we found the irst, the irst has been carried to the endrof the trough upon the bevellcd bottom, the lugs have struck the buttons, and the stop has shot up, 'and now prevents the half-finished (first) shingle from going back.

vThecarriage is again startedback, as before, when the roller in its spring-frame holds the shingle down, while the knife lcy begins to shave the top side, the shaving passing out over the top of the knife, and over the roller n, with vits drag oB 'The carriage is sent clear back, and the operation commenced again, all

the drags dropping when the carriage has gotten home,

U takes hold ofthe second shingle, V takes the shaving from the first shingle, and 0 takes the first shingle itself.

The operation renewed again, the drags carry the finished shingle and shaving out of the way and bring the second one along to occupy the place vacated by the first, while the third is being cut, and. so on, the shavings taken from the under side passing ont between the sections D of the bottom.

Having described the construction and operation of my improved shingle-machine,

What I claim as new, and desirev to secure by. Letters Patent, is y f 1. The dragdifter M, secured to the carriage-flame, by staples S, and travelling with the carriage, the level' N, and drags U, .V, and o, arranged as described, and operated by the groove c, lever NV, and stop-frame S, and its-pin x, substantially as and for the purposes set forth. C

2. The upper rails B, provided with the slots a b, constructed as described, iu combination with the gate or block O, with its vertically moving head Q, provided withv pins, to travel in groove b, and rightangled clamps 2,1'odP, and loops t t, all arranged gud operating in the manner and for the purposes set orth.

3. The stop-frame' S, provided With the stop g and pin x, performing the double duty-of arresting the shingle, `and lifting the drags, automatically, in the manner and for the purpose set forth.

4. In combination with the above, the knifek and roller J, as and for the purposes set forth.

5. The carriage-frame, moving inside of the ways,

- and provided on their exterior sides with the grooves i, so .constructed that one end shall move over and raise and. lower the lower shaving-knife f, and the other travel over the piu x, on the stop-frame, raising and lowering it automatically, and with reference to the -movement of the knife f, in thev manner and for the purpose set forth.

Ip testimony whereof, I have hereunto set my hand and seal, this 24th day of July, A. D. 1869.
